Sweet spot
A builder-run principal contractor on a domestic or commercial project who needs ready-to-sign CDM documents, worker sign-off, a live people-on-site view, practical site files, subcontractor evidence records and lightweight inspections/actions - without a dedicated H&S department to run them.
Strengths
UK construction compliance tool that ships RAMS + CPP + COSHH + inductions (readable and acknowledgeable in 9 worker languages on Business, with the language audit-recorded) + worker sign-off, including optional 4-digit shared-link PIN evidence on Business, plus site attendance, portal users, site files, document reviews, subcontractor evidence and inspections/actions.
Generate a site-specific RAMS first draft from a natural-language brief in under five minutes, ready for competent-person review - not a template library you hand-fill.
Controlled document workflow without an enterprise contract: version history and a recorded issue confirmation before a document is shared with a client or downloaded in the app on every plan, re-sign on revision with superseded signatures preserved plus PCPP import, cert tracking and document checking from the £39/month Pro plan - and on Business, optional named-approver routing (a designated approver accepts or rejects each version, with recorded reasons, before it can be issued) plus client approve/reject/request-changes via share links.
Transparent pricing: Starter £0, Pro £39/month or £360/year, Business £199/month with 10 management logins and 50 active site portal users. Worker document signing has no per-signature charge; project workers count as active portal users while assigned.
Build RAMS for any trade - add your own work types and method statements alongside the built-in library, reusable across projects, including a ready-made Commercial Solar PV group. Save a finished job as a reusable project template, or clone it, so the next job of the same shape starts from your own setup.
COSHH goes deep: a standalone COSHH assessment document, upload-a-Safety-Data-Sheet extraction, a site-specific substance register and an expert-reviewed library - plus per-worker RAMS sign-off and a one-click Audit Pack covering documents, sign-offs, worker evidence, attendance, incidents, COSHH, permits and up to the latest 500 live Site Diary entries.
Weaknesses
New product (launched 2026) -smaller customer base and shorter track record than established tools like HandsHQ.
Procore integration is in final testing rather than publicly launched -until it ships, compliance docs export as PDFs rather than syncing into Procore. A public REST API and signed webhooks are live on the Site Control tier; Autodesk Construction Cloud is not integrated.
Site files are a practical portal for drawings, plans and procedures, not formal drawing revision control.
UK-focused content (CDM 2015, HSE guidance) -international contractors on non-UK projects would need to adapt the output.

Sole trader to small/mid building companies (Foundation ≤9, Complete unlimited)
Sweet spot
A small UK builder who wants safety made simple, with an advice line and a QR Hazard Board for site sign-in, on a low flat annual fee.
Strengths
Transparent, low, all-in annual pricing (£468–£828/yr) that bundles the software, app and an unlimited human H&S advice line — an easy yes for a small builder.
Human advice line and guided incident response — a service layer that pure-software tools lack.
Mature, proven product at scale (10,000+ businesses / 150,000 users across AU/NZ) with an FMB partnership for UK credibility.
Strong physical-plus-digital site sign-in: a QR Hazard Board for one-tap induction and daily scan-in.
Weaknesses
Gaps versus a full UK CDM suite — no visible COSHH, CSCS/worker-cert tracking, right-to-work or permit-to-work features.
Non-UK origin with a young UK presence (live only since late 2024) and no named UK legal entity on the site.
Annual lump-sum plus per-project add-ons (from £40/project) make heavy-project costs less predictable than a flat subscription.
Short, straight answers - the same questions real builders ask.
Is HazardCo cheaper than The Site Book?
For a simple annual membership, HazardCo can be cheaper: Foundation is GBP468 per year and Complete GBP828 per year, though projects add from GBP40 each. The Site Book charges from GBP39 per month or GBP360 per year up to GBP199 for Business. Which is cheaper depends on project volume; HazardCo's per-project add-ons make heavy-project years less predictable than a flat subscription.
Who should choose HazardCo?
Choose HazardCo if you are a small builder who wants safety made simple with human hand-holding. Its unlimited H&S advice line, guided incident response, FMB partnership and a mature, proven product at scale are real strengths, alongside a QR Hazard Board for one-tap induction and daily sign-in. The Site Book suits builders wanting AI-generated documents and deeper self-serve site operations.
Does HazardCo cover COSHH and the wider CDM document set?
HazardCo generates site-specific RAMS and a Construction Phase Plan, plus QR inductions, toolbox meetings and incident reporting, but it does not publicly offer COSHH assessments, certificate or right-to-work tracking, or permits to work. The Site Book adds a standalone COSHH document with Safety Data Sheet upload, certificate and right-to-work evidence, permits, and AI generation of that wider CDM document set.
Does HazardCo include a human advice line?
Yes, and it is a genuine strength. HazardCo bundles an unlimited human H&S advice line and guided incident response into its annual fee, a service layer that pure-software tools lack, backed by its FMB partnership. The Site Book does not offer a human advice line; instead it provides AI-generated documents, an AI chat surface, and deeper self-serve site operations, portal access and audit tooling.
Can HazardCo replace The Site Book for CDM projects?
It can for a builder wanting guided, simple safety with advice on tap. HazardCo covers RAMS, a CPP, QR inductions, attendance and incident reporting well. The Site Book goes further on the document set and site operations: COSHH, permits, certificate and right-to-work tracking, subcontractor evidence, site files, inspections and a one-click Audit Pack covering compliance evidence plus up to the latest 500 live Site Diary entries.
